have you read this book before?

have you read this book before?
yes i have
no i havent
是不是错的?
就象did't you speak to him yesterday?
yse i did
no i didn't一样
是不是应该是haven't you read this book before?

我想很多朋友都理解错了楼主的问题.楼主想问的应该是关于反义疑问句的问题.
这个问题是中国人常搞不清楚的一个问题
这是因为英文是对事实本身回答yes或no
比如didn't you speak to him yesterday?你昨天没和他说话吗?
回答yes,i did.是说我和他说话了,这里yes是对说话这件事表示肯定
而中国人回答是对提问的整个句子表示肯定或否定,回答“是的,我没有”这里“是的”是对提问者的问话表示肯定,意思是,“你说对了”
所以不管你是问didn't you speak to him yesterday?还是did you speak to him yesterday?回答都是yes,i did或no,i didn't.表示的意思也是一样的“是的,我和他说话了”“不,我没和他说话”
对于提问者来说,否定疑问（didn't you）有一定的反诘疑问,有“难道你没...”的意思,但不一定很强烈.有时就和did you一样.
对于时态,这里用完成时后面跟before没有任何问题.字典里的例句就是i have never met him before.
